I bought "The Ice Princess" from Amazon (eBook. AZW DRM +) and I want to read it on Calibre.
When I try to do the conversion, Calibre tells me that it is impossible because "The Ice Princess" is protected by DRM.

1. Do something illegal (crack the DRM). Don't do this. It's unethical. After all, you'll be costing Amazon at least $0.00. Imagine if everyone did this. Multiply that $0.00 by thousands, maybe even millions! All because you had the audacity to expect to make use of something you purchased from them.

OR

2. Accept that you've sold your soul to Amazon and are now locked into their self-reinforcing ebook - reader system with no hope of ever escaping unless you want to re-purchase your library (which will just sell your soul to someone else).
